Drew Eppehimer was featured in a video and news articled by the US Geological Survey on the U.S. Fish and Wildlife Service and Bureau of Reclamation’s work to protect Grand Canyon ecosystems from invasive smallmouth bass. From modeling fish population growth to forecasting the effects of future dam operations, the USGS’s unbiased, high-quality science helps on-the-ground managers rise to new challenges brought on by climate change.

Drew graduated from the ALRS GIDP in 2021, with a focus in Aquatic Ecology. He is now a fish biologist with the USGS Southwest Biological Science Center's Grand Canyon Monitoring and Research Center in Flagstaff, AZ. His research examines the environmental drivers of fish populations in the Colorado River Basin. Drew's research interests broadly span aquatic ecology including fish and invertebrates in both lakes and rivers. His research examines coupled human-natural systems such as artificial and regulated river systems and currently focuses on how drought, water storage, and reservoir operations impact biological invasions in the Colorado River Basin. His models quantify invasion risk and inform smallmouth bass management efforts in the Grand Canyon.
